Abstract: A method of determining the location of a user in an area. A user requests a transmitting device from a transmitter providing device. The transmitter providing device associates an identification code with the user, and the transmitting device transmits that identification code. One or more of receiving devices receive the identification code transmitted by the transmitting device, and send details of the received identification code to the user location determining device. The user location determining device then determines the location of the user, using the received details from the one or more receiving devices.

Abstract: An interactive electronic device includes a display module designed to display a graphical interface on a display surface, a detection module designed to determine a position of a user interaction element in a preset detection module volume and a processing module suitable for controlling the interactive electronic device as a function of the determined position of the interaction element according to at least a first operating mode. In the first mode of operation, a projected surface, corresponding to the orthogonal projection of the preset detection volume on the plane including the display surface, is offset from the display surface of the graphical interface.

Abstract: A drive-thru system includes a kiosk equipped with at least one omnidirectional antenna and at least one directional antenna, and a user equipment equipped with a processing unit and a communication unit.
